### ⭐⭐⭐⭐⭐ Good deal

Simple instructions my girl could follow. Everything where it should be. A good intro to hand building things.

### ⭐⭐⭐⭐ Good Quality and Value
*by B***S on September 12, 2024*

Happy with this purchase. This woodworking craft kit is pretty good quality, and the cost is reasonable, since 4 builds are included in this purchase. We got this item for our Cub Scout Pack (grades K - 5) and the build itself is mostly appropriate for this age/grade range. It takes the scouts about 30 - 40 minutes to build one of these robots, which is a perfect amount of time to fit into a pack meeting schedule. Minor critiques... the product says that it's appropriate for ages 3 and up, but in my opinion this build is best for ages 5 and up. Some parent/adult help is needed even for 5 and 6 year-old kids. It would have been nice if the directions and stickers for each robot build were "pre-sorted" (bagged with) the wooden building blocks instead of us having to sort these items into 4 separate groups. Also, it would have been helpful if the directions contained even just a little bit of text to help the kids interpret some of the step-by-step building images.
